Data Security
• Power down your host computer and all attached peripheral devices before beginning installation.
• Each enclosure contains up to 12 removable disk drive modules. Disk units are fragile. Handle them with care, and keep them away from strong magnetic fields.
• All the supplied plug-in modules, dummy carriers and blank modules must be in place for the air to flow correctly around the enclosure and also to complete the internal circuitry.
• If the subsystem is used with plug-in modules, dummy carriers or blank modules missing for more than a few minutes, the enclosure can overheat, causing power failure and data loss. Such use may also invalidate the warranty.
• If you remove any drive module, you may lose data.
• If you remove a drive module, replace it immediately. If it is faulty, replace it with a drive module of the same type and capacity
• Ensure that all disk drives are removed from the enclosure before attempting to manhandle or move the rack installation.
• Do not abandon your backup routines. No system is completely infallible.
Special Tools and Equipment
There are no special tools required but in order to complete the assembly of some configurations you may need the following:
• Security keys (one of these should be included with your SR1202 enclosure for use with the drive locks).

Figure 10. SR1202 Enclosure
14 15MAXDATA SR1202 M1 – Technical User GuideIntroduction
The Enclosure Core Product
The SR1202 design concept is based on an enclosure subsystem together with a set of plugin modules. The SR1202 Enclosure Platform as supplied comprises:
• Chassis and Backplane with integral (front panel mounted) Operator’s Panel (see Figure 11)
• Up to 12 Drive Carrier Modules (see Figure 21), containing either:
– 3.0 Gb/s direct dock SAS disk drives,
– 3.0 Gb/s direct dock SATA disk drives, or
– 3.0 Gb/s dual path SATA disk drives via an active/active SATA mux transition card
• Two plug-in Power Supply Modules,100–260 V AC, 350 W (see Figure 14)
• One plug-in Cooling Fan Module
• Two plug-in SR1202 RAID Controller Modules (see Figure 17), incorporating a SR1202 RAID Controller and a StorView® Management Module.
NOTE
If only one SR1202 RAID Controller Module is installed then a Blank (SR1202) module must be fitted in the unused slot.
Enclosure Chassis
The chassis consists of a sheet metal enclosure assembly containing a Backplane printed circuit board (PCB) and module runner system.
• The chassis front panel incorporates an integral Operator’s (Ops) Panel.
• The Backplane PCB provides logic level signal and low voltage power distribution paths.
• Figure 11 and Figure 12 show front and rear views of a populated chassis respectively.
• The chassis is fitted with 19 inch Rack mounting features which enable it to be fitted to standard 19 inch racks and uses 2 EIA units of rack space (i.e. 3.5” high).
The chassis assembly contains 12 drive bays at the front, each of which accommodates the appropriate plug-in drive carrier module. The 12 drive bays are arranged in 3 rows of 4 drives. At the rear, the chassis assembly contains four plug-in module bays to house two Power Supply modules, a Cooling Fan module and two SR1202 RAID Controller Modules which are fitted horizontally (one above the other) in the fourth bay, as shown in Figure 12
NOTE
A drive bay is defined as the space required to house a single 1.0“ high 3.5 inch disk drive in its carrier module. e.g. a 1 x 3 bay module would take the space of 1 drive width by 3 drive bays high (in rack mount configuration), shown in Figure 11.
Figure 12. Enclosure Chassis (Rear)
Operator’s Panel
The enclosure front panel incorporates an Operator’s (Ops) Panel with four LEDs, see Figure 13. The Ops Panel provides the user with a high level indication of the operation of the Enclosure. Please refer to Table 9, ”Ops Panel LED States”, on page 41 for details of the LED status conditions.

The functional modules have associated status LEDs. The Ops Panel shows a consolidated status for all modules.
LEDs show constant Green or Blue for good or positive indication. Constant or flashing Amber LEDs indicate there is a fault present within that module.
Table 1. Status LEDs
LED State Description
Power On
Constant Green Good or positive indication
System Fault Constant Amber: fault present Indicates a problem with a Power Supply,
Cooling or RAID Controller Module. Refer to individual modules that contain individual fault LEDs, see Table 7 on page 40, Table 8 on page 40 and Table 10 on page 42
Logical Fault Constant Amber: fault present Indicates failure of a drive module. The
module failing will be indicated by the Fault LED, see Table 11 on page 43
Box Identity
Constant Blue: enclosure identity The user can illuminate this via the
Management intefaces to indicate which enclosure requires service actions to be performed on it.
Please refer to Table 9 on page 41 for a description of the Ops panel LED states.
Audible Alarms
The SR1202 enclosure includes an Audible Alarm which indicates when a fault state is present. The following conditions will activate the Audible Alarm:
• Fan Fault
• Voltage out of range
• Over temperature
• Thermal overrun
• System fault
• Logical Fault
• PSU Fault
• Removal of 1 PSU
• Invalid cabling
When the Audible Alarm sounds, it may be muted by pressing the Alarm Mute push-button which is incorporated in the enclosure front panel. Please refer to section “Audible Alarm Mute” on page 43 for more information on this function.
The Plug-in Modules
An SR1202 Enclosure requires the following modules for normal operation:
• 2 x 350 W AC Power Supply modules
• 1 x Cooling module
• 1 or 2 x SR1202 RAID Controller Modules
• Up to 12 Drive Carrier modules.
• Dummy Drive Carrier modules, as required.
NOTE
No drive bays should be left completely empty, dummy carriers and/or blank modules must be fitted in all unused bays.
AC Power Supply Module
Two 100 V–260 V AC 350 W Power Supply modules (Figure 14) are supplied mounted in the rear of the enclosure as part of the enclosure core product.
Figure 14. AC Power Supply Module
18 19MAXDATA SR1202 M1 – Technical User GuideIntroduction
PSU voltage operating ranges are nominally 115 V or 230 V AC, selected automatically.
Two LEDs mounted on the rear panel of the Power Supply module (see Figure 14) indicate the status of the module:
Table 2. Power Supply LEDs
Power On & OK (Green)
Module Fault (Amber)

Off Off No AC power (either PSU)
Off
On No AC power (this PSU only)
Off
On PSU Fault (over temp, over volts, over current, PSU fan failure)
On Off AC present, PSU on OK
On On Fan Fault
Multiple Power Supply Modules
The SR1202 must always be operated with two Power Supply modules fitted. The two Power Supply modules operate together so that if one fails the other maintains the power supply and cooling while you replace the faulty unit.
Module replacement should only take a few minutes to perform but must be completed within 10 minutes from removal of the failed module.
Cooling Module
The Cooling Module provides system cooling, thermal monitoring and control functions.
System airflow is from front to back of the enclosure:
• Cooling airflow passes over drives and through the midplane to a central plenum.
• The cooling module pulls air from the plenum and from the RAID Cnotroller Modules.
• The PSUs pull cooling air from the plenum at the rear of the enclosure.
NOTE
The system must be operated with low pressure rear exhaust installation (back pressure created by rack doors and obstacles not to exceed 5 pascals [0.5 mm water gauge])
The module incorporates an amber Cooling Module Fault LED, defined in Table 3
